France Transfo proposes AtEx electrical transformers which are designed for aboveground industries where there is a low probability of explosive atmospheres in the form of gases.

The level of protection required is normal with respect to the normal operation of the equipment.
The explosive gas that may be present in the atmosphere is propane, butane, methanol or industrial methane.
The surface temperature of the equipment in normal operation is always below the auto-ignition point of the gases present in the area i.e. 200º C for T3.

A whole range of equipment suitable for ATEX environments and certified by an independent laboratory, in accordance with the ATEX European Directive 94/9/EC

Transformers immersed from 250 to 2000 kVA
- sealed tank
